• The kinetics and controllability of the Ti[OCH2CCl3]4‐initiated atom transfer radical polymerization (ATRP) of n‐butyl acrylate were investigated. Then, with Ti[OCH2CCl3]4 as the initiator, poly(ϵ‐caprolactone)‐block‐poly(n‐butyl acrylate) (PCL‐b‐PBA) copolymers were synthesized by the combination of the ring‐opening polymerization (ROP) of ϵ‐caprolactone and ATRP of n‐butyl acrylate. With different sequential combinations of ROP and ATRP, three routes were used to synthesize PCL‐b‐PBA copolymers. The composition characterization results demonstrated that the first‐ROP‐then‐ATRP route was most efficient; it was followed by the in situ ATRP and ROP route and then the first‐ATRP‐then‐ROP route. Furthermore, with a Haake Rheomix reactor (Thermo Electron Corp., Karlsruhe, Germany), the PCL‐b‐PBA copolymers were in situ synthesized in a poly(methyl methacrylate) matrix. © 2009 Wiley Periodicals, Inc.
